Please help!
This guy fell on the windshield my car (I did not notice) and rode with me some distance. What is it? If I cannot find its host plant soon, I don’t know what I can do for it. I have tried feeding it a variety of plants to no avail. It is super tiny and very hard to get a good picture. I hope these pictures can assist!

Sawfly Larva

Sawfly Larva

Dear Rachel,
Though it resembles a Caterpillar, your insect is actually a Sawfly Larva, a relative of wasps and bees from the order Hymenoptera.  According to About Education:  “Caterpillars are the larvae of butterflies and moths, which belong to the order Lepidoptera. Sawfly larvae look similar to caterpillars, but are an entirely different kind of insect. Sawflies are related to bees and wasps, and belong to the order Hymenoptera. Like caterpillars, sawfly larvae usually feed on plant foliage.  How can you tell the difference between a sawfly larva and a caterpillar? Count the prolegs. Caterpillars may have up to five pairs of abdominal prolegs (see parts of a caterpillar diagram), but never have more than five pairs. Sawfly larvae will have six or more pairs of abdominal prolegs*. …  There are, of course, exceptions to every rule. Caterpillars of the family Megalopygidae, the flannel moths, are unusual in having 7 pairs of prolegs (2 more pairs than any other Lepidopteran larvae). ”  Your individual appears to have at least seven pairs of pro-legs.  Based on this BugGuide image, we believe your individual may be a Raspberry Sawfly,
Monophadnoides rubi.  If that is the case, according to BugGuide, you should try feeding it rose leaves if you cannot locate raspberry leaves.

Thank you so much for this information! This is so helpful. I had no idea! Wow.
We tried a blackberry leaf earlier. I will go find some rose leaves.
Thank you! Thank you!

Hi. Found a new wasp sp. in my backyard. Looks somewhat like a Popper Wasp, back lacks yellow legs etc. Any thoughts?

Bottlebrush Sawfly

Bottlebrush Sawfly

Dear Tim,
This is a Bottlebrush Sawfly,
Pterygophorus cinctus, and we previously misidentified as possibly a Potter Wasp ourselves once.  Your image is quite beautiful.

Thanks Daniel!
I’ve been having a bit of a influx of fly/wasp type sp. into my inner suburban Melbourne (Aust) backyard this summer, including Banded Beefly, Wasp-mimic Hoverfly, as well as other more common hoverfly and butterflies such as Common Darts. Very unusual but very fascinating!
Cheers,
Tim

Wood Wasp

Wood Wasp

Dear Paula,
Do you have firewood in the house?  We believe this Wood Wasp and its coevals emerged from firewood because their normal development was accelerated due to the heat indoors.  Your individual is most likely in the genus
Xiphydria, and because of its dark antennae, it most closely resembles the images of Xiphydria tibialis posted to BugGuide.

Yes we do…Thank you very much my husband thought it looked like a form of a wasp..hope they don’t sting …thank you so much for the quick response 🙂

Hi there,
This is just a reiteration of an earlier question you got that I also saw. I live about an hour north of Tampa, FL, and saw the same larvae as the one in this photo:
https://www.whatsthatbug.com/2014/02/11/orange-larvae-caterpillarf-sawflies/
I thought my photos would be a good complement to the others already provided and may help someone else seeking the ID of this bug. The larva moved quickly, but I did not find what they were feeding on. I found them in the vicinity of our cactus garden, but I found they were more on a piece of driftwood than any of the cacti. I only saw them crawling around at that one specific time and don’t believe I caught sight of any others in our garden after that encounter (but there were plenty during that encounter, crawling around quickly but aimlessly). Unfortunately, I did not get a photo of their prolegs that I can find.
This was in late January of last year (so approximately 1 year ago). I haven’t seen anything this year so far, though!
Thanks, and good luck fighting the good fight!

Sawfly Larva

Sawfly Larva

Dear Fellow Buglover,
Thanks for providing additional images similar to those from a previous posting.  We believe both examples are Sawfly Larvae, and both look very similar to this BugGuide image identified as being in the genus
Arge.  Can you provide any information on the size of the individual?

Dear Jerry,
This female Pigeon Horntail died while laying eggs.  She probably could not extract her ovipositor from the tree trunk.

Dear bug man,
A friend found this bug and I’m having a hard time finding what it is with the help of Google (haha) hoping you might be able to shed some light on us. Thank you so much for your time. 🙂

Asian Horntail

Asian Horntail

Hi Lena,
We are going to have to go with “other” on this identification.  This is an Asian Horntail,
Eriotremex formosanus, which we identified thanks to this image posted to BugGuide.  According to BugGuide:  “introduced accidentally with wood (crates, etc.); first reported in 1975” and the larvae feed on “hardwoods (oak, hickory, sweetgum, probably others); attacks mostly dead/dying wood, so not a serious pest.”  Additional information can be found on Featured Creatures.
